r This invention relates to improvements in pyrophoric lighters of thepocket type in which is embodied novel means for making a spark andproducing a flame.

An object of my invention is to provide a pocket sizcpgrrophoric lighterwherein is compactly cm died novel means for roducing a spark for theigniting of a wic Another object of my invention is to provide apyrophoric lighter having the various operating parts thereof compactlycontained in' a casing resembling a pen in 'shape.

Another object of my invention is to provide a combined cigaretteholder,p(yrophoric lighter and pen, all bein embo ied in a convenientand compact orm suitable for carryin in a vest ocket.

Another object oi m invention is to provide a combined pyrop oriclighter and cigarette holder, embodying a construction which permits theconvenient use of the lighter without its detachment from the cigaretteholder.

Other objects more or less apparent will present themselves or will bespecifically ,pointed out in the description to follow.

" In the accompan g drawings illustrating;the:preferred orm my inventionmay .assume: I

Fig. 7is, aside elevation of my improved pyrophoric lighter with a penattached thereto, showing a part of the casing broken away and in crosssection.

Referring to the drawings, the numeral 1 represents an oval shapedcasing having a o detachable end piece 2 screwed into one end thereofand an enclosin end member 3 located at the other en Attached to the endmember 3, as by screws 4, is a-circular shaped tubular member 5, whichhas one of its ends bent inwardly as at 6, and its oppo- -for the iiting of'the end 0 site end closed by a partition 7. An extension 8,-which forms a part of the tubular member 5, is provided with a largeopening 9 in its side. Movably located at the end of the extension .8 isa cap piece 10 which is provided with a projecting part 11 that ismovably located inside the said extension 8. The projecting part 11 isprovided with a cut away part which forms an opening 12 of approximatelythe same size as the large opening 9 in the tubular member 5. Secured tothe end member 3 and'to the partition 7, with its end extending beyondthe latter, isa wick tube 13which carries a wick 14.' Also extendingthrough the end member 3 and the partition 7 is a tubular member 15having one of its ends closed and a pyrophoric bar 16 projecting fromandbeyond its other end. A spiral spring 17 havin one end bearin againstthe closed end 0 the tubular mem r 15 and its other end pressing againstthe pyrophoric bar 16, serves to resiliently maintain the latter in anoutwardly projectin position.

. Movably extending through the partition 7 and a tubular projection 18located on the latter, is a pin 19 having a square end 20 which extendsthrough a steel disc 21 and the cap piece 10. A screw 22, with its headlocated on the outside of the cap piece 10, is adapted to screw into thesquare end 20 of the pin 19, thereby providing suitable means formaintaining the steel disc 21 inside the cap piece. The pin 19 is formedwith an enlarged central section which provides shoulders that arelocated against the steel disc 21 and the partition 7. A spiral spring23 encircles the circular projection 18 and is secured at one end to theend of pin 19 and at its opposite end to the wick tube 13. The. steeldisc 21 is provided with a plurality of small teeth 24 which contactwith the end of the pyrophoric bar 16 and are adapted to co-operate withthe latter to produce a spark the wick 14.

Movab y mounted on'the tubular member 5 and suitably held in position,as by projections-25, is a ring 26 which is provided with an inwardlyextending projection 27 which passes through alslot located in the sideof the tubular member 5.

,Movabl located inside a tubular projection 28 w ich is secured to theartition 7, is a bar 29 which is provided a jacent the projection 27with a. pawl 30 and at its op- 110 posite end with a latch member31which 15 located insideand adjacent the end of the rejecting part 11of the cap piece 10. The atch member 31 is adapted to engage with turnthe bar 29 so the latch member 31 may" be released from the projection32.

As shown in Fig. 1, the casing 1 is slidably located in a tube 34 andthe same is adapted to be pulled outwardly to light-a cigarette whichmaybe inserted in the end of a cigarette holder 35, the latter beingattached to the tube 34 by bands 36.

The end piece 2 may be substituted'for a tubular extension 37 which isadapted to receive a pen or pencil 38. I 3

As illustrated on the drawings the lighter isin a closed position withthe openings 9 and 12 closed, and the spiral spring 23 in a wound upposition. To produce a spark for the igniting of the wick 14 and tobring into registration the'two large openings 9 and 12 respectively, inthe extension 8 and projecting part 11, the ring 26 is turned by thehand so as to cause the extension 27 thereof to move the pawl 30. As thering is turned and the pawl moved, the bar 29 is also turned. and thelatch member 31 is released from the projection 32 of the projectingpart 11. This then permits the pin 19, the cap piece 10, the steel disc21 and the projecting part 11 to be turned by the spring 23 which isfastened at its ends to the pin 19 and to ,16, thereby producing a sparfor the i ition of the wick 14. As the cap. 10 an its projecting part 11are turned, the opening 12 in the latter is brought around to a positionwhere it coincides with the opening 9 in the extension 8 of the tubularmember 5. When the two openings are in this position the flame from theignited wick 14 is allowed to pass therethrough for the lighting of acigarette.

To close the openings '9 and 12, the cap piece 10 is turned in tieopposite direction to a position which causes the rejection 32 to engagewith the latch mcm r 31." The turning of the cap piece in' thisdirection causes the spring 23 to again become contracted preparatory tothe next lighting operation.

It is obvious to those skilled in the art that my improved pyrophoriclighter may be embodied in. other forms than the one shown and describedherein, so for this and other reasons it is desired that my invention beincluded broadly within the spirit of the appended claims.

Having described my invention, what I claim is:

' -1. A pyrophoric lighter comprising a casing having a partition.memberlocated therein and an opening located adjacent an end thereof, a wickprojecting through the partitionmember, a pyrophoric element projectingfrom the partition member ad- .jacent the wick, a cap having an openingin its sides which is adapted to coincide with the opening in thecasing, which said cap is pivotally attached by a pin to the partitionmember, a friction member secured to the cap and in contactwith thepyrophoric element, and a spring attached at one of its ends to the pinfor rotating the cap, the pin and the friction member, whereby thefriction meml *r may be moved against the pyrophoric eleinent to producea spark for ignitingthe wick.

2. A pyroplioric lighter comprising a casing carrying a pyrophoricelement and a wick, a cap pivotally attached hya pin to the casing, afriction member secured to the cap and in contact with the pyrophorieelement, a spring attached to the pin which said spring may becompressed by turning the cap, mea'ns engageable withthe cap formaintainin the cap against rotation by the spring, ant means foractuating the first mentioned means, whereby the cap and the frictionmember may be rotated by the spring.

3. A pyrophoric lighter comprising a casing, a tubular member secured tothe easing having an enclosing end men'lber, a wick projecting beyondthe end member, a pyrophorie element projecting from the end member at apoint adjacent the wick, a cap carrying a friction member pivotallyatattached-to the end member, the friction member being in contact withthe pyrophoric element, and a spring connected to the cap and thetubular member for rotating the cap and the friction member, whereby thefriction member may bemoved against the pyrophoric element to produce aspark for igniting the 'wick.
